Even though lampas is a type of double weave, it has a definite right and wrong side. Sometimes you might choose to use the "wrong" side as an accent or contrast, but in general this is a one-sided fabric, good for upholstery, lined garments, table linens, etc.
Following are a few of my samples with right and wrong sides shown. Right side is on the left, wrong side to the right. Click to enlarge.
